title: HPV status after cold knife conization.
abstract: BACKGROUND
  The aim of this study was to determine whether HPV DNA test after cold knife conization is a predictive factor for CIN persistence or recurrence. The study also investigated whether HPV DNA test results should influence post cold knife excision surveillance.
  
  
  METHODS
  A retrospective observation study was performed on 738 patients who underwent cold knife conization for CIN or microinvasive cervical cancer at the University Clinic of Obstetrics & Gynecology, Medical Faculty, Ss. Cyril and Methodius University, Skopje from 1st June 2007 to 1st June 2009. A total of 217 patients met the inclusion criteria and were with complete data. The follow-up HPV DNA testing was performed at 8 months after cold knife conization, after which the patients were followed-up every 4 months till 24 months postoperatively.
  
  
  RESULTS
  HPV DNA testing after 8 months after conization showed that 44 patients were HPV DNA positive and 199 were HPV DNA negative. Recurrent cytological abnormalities were found in 26 of the 44 HPV DNA positive patients, and in 12 of the 199 HPV DNA negative patients. Analysis showed that a positive HPV DNA result was a risk factor for recurrent/persistent cervical intraepithelial neoplasia.
  
  
  CONCLUSIONS
  HPV DNA testing 8 months after conization is important for predicting the risk of disease: persistence or recurrence. In addition, such testing can assist in designing patient management, since HPV DNA negative patients should undergo routine surveillance, while HPV DNA positive patients should undergo frequent and meticulous surveillance.
